Secondary containment systems are protective measures designed to prevent leaks, spills, and contamination. These systems usually use a barrier, like an HDPE/RPE liner, surrounding tanks, drugs, or other storage containers. This barrier traps and contains any leaked or spilled material from a primary containment system.
These kinds of secondary containment systems are especially important in industries that handle hazardous materials. Using a secondary containment system helps to mitigate environmental risks, and is often required by regulation.
